Defines the visible 3D volume and the 2D screen area that a 3D volume projects onto for the GetViewport and SetViewport methods.

When the viewport is changed, the driver builds a new transformation matrix.

The coordinates and dimensions of the viewport are given relative to the top left of the device.

See also d3dViewport.

Dimensions of the viewport.

dvScaleX and dvScaleY

Values describing the scaling quantities homogeneous to screen.

dvMaxX, dvMaxY, dvMinZ, and dvMaxZ

Values describing the maximum and minimum homogeneous coordinates of x, y, and z.
